A recent study published in the Journal of the American Dietetic Association found that cognitive behavior therapy (CBT) for weight loss produces healthier eating habits and motivation for physical activity in adults and their adult family members. In the current study, CBT treatment positively influenced weight, food choices, and physical activity among participants and family members (mainly spouses). The significant correlation between participants and their spouses, in terms of weight loss and positive lifestyle habits, suggests that family support may be an important mechanism contributing to favorable outcomes of treatment.
